To order specifications other than those listed in this datasheet, contact our sales staff for more information.

EPR series can be easily installed up to five units with RMO series, rack mount adaptor (sold separately, Model No. RMO-133H-EPR).

Remote Control Connector (Control)

D-Sub 15-pin female (mating connector enclosed).

Remote/Local change

Output	External relay	Open collector
Remote	Short	VCE ≤ 0.4 V
Local	Open	VCE ≥ 2 V

Sink Current ≥ 10 mA

External output ON/OFF

Output	External relay	Open collector
ON	Short	VCE ≤ 0.4 V
OFF	Open	VCE ≥ 2 V

Sink Current ≥ 10 mA

• When Output state auto-recovery prevention (former: power failure protection) is ON: Outputting of high voltage is possible only when both of OUTPUT switch and external output ON/OFF are ON.
• When Output state auto-recovery prevention (former: power failure protection) is OFF: Outputting of high voltage is possible when external output ON/OFF is ON. (under remote control)

Output Control remote analog programming

Output voltage	Vcon
0 to Maximum	0 to 10 V Input impedance ≥ 1 MΩ

Output current	Icon
0 to Maximum	0 to 10 V Input impedance ≥ 1 MΩ

Output monitor

Monitor output is 0 to +10 V for 0 to Max. Output impedance 1 kΩ

Interlock

It is possible to output in external relay short or a status of V_CE less than 0.4 V. Output will be cut off when open or 2 V or more. To resume the output again, turn the power switch ON after resetting by turning the power switch OFF in a status of short or less than 0.4 V

Sink current ≥ 10 mA

-LDe

Pulse/Ramp Sequence
Following output controls of A to C are applicable.

A. Pulse Sequence

Sequential operation is possible by using voltage and current set on each memory a, b, and c in combination with multi-set functions. Not only continuous operation, but also it is possible to specify the times.

It is the best-fit evaluation test for products as various operations, like as repeat of a and b only or a repeat of b, c and off only, are enabled by setting time of memory a, b, c or off to 0.0.

ta, tb, tc, and toff can be set respectively in 0.0 s to 9999 h 59 m 59.9 s.

B. Ramp

It enables to make ramp action up to the set voltage or current (or from the set voltage or current to 0 V or 0 A). It is useful to like to increase/decrease voltage or current slowly.

* As for the lamp operation, you can select "Both setting voltage and current", "Voltage setting only", or "Current setting only".

t1 and t2 can be set respectively in 0.0 to 9999 h 59 m 59.9 s.

C. Combination of Pulse and Ramp Sequence

It is also possible to use pulse sequence combined with ramp action. If the multi-set function is combined with the too, it is able to make sequence action by using voltage or current set on memory a, b, and c. Not only continuous operation, but also it is possible to specify the times.

It is useful in various aspects as it is possible to increase/decrease voltage or current slowly up to 20 set values.

t1 to t4, ta to tc and toff can be set respectively in 0.0 s to 9999 h 59 m 59.9 s.

-LGob

Optical Interface Board
With optical communication, galvanic isolation control is performed. As complete isolation is performed by means of optical fiber, this enables advanced prevention of erroneous operation involved with transient phenomenon caused by surges, inductive lightning, external noise, etc.
And, the control via the SCPI command is also available.

• -LGob: Optical interface board + optical cable 2 meters
• -LGob(Fc5): Optical interface board + optical cable 5 meters
• -LGob(Fc10): Optical interface board + optical cable 10 meters
• -LGob(Fc20): Optical interface board + optical cable 20 meters
• -LGob(Fc40): Optical interface board + optical cable 40 meters

Select the optional optical interface board (-LGob) when using this high voltage power supply under the following conditions.

• Noisy environment including factories (Example: Motors or coils are used near power supplies and loads).
• Using with high voltage floating (more than 250 V).
• Installation distance of 2 meters or more between the high voltage power supply and a controller such as a computer, laptop, or Programmable Logic Controller (PLC).

Adapters (sold separately)
